Application of Computer Modeling for Harbor Resonance Studies of Long Beach & Los Angeles Harbor Basins
Year: 1999
Type: conference-paper
Abstract: One of the major engineering problems for large harbors with container ship operation is the motion of moored ships due to long wave activity. In order that the wave-induced ship-motions may be effectively controlled, the response characteristics of the harbor basin due to incident waves must be accurately determined. This study focuses on the application of a computer model in the harbor resonance study in connection with modification of harbor basins. The computer model used is a finite element model with the mild-slope equations as the governing equations. Various boundary conditions are incorporated in the model: fully and partially reflecting boundaries, permeable boundary. Energy losses across the harbor entrance due to flow separation and frictional loss at the bottom are also incorporated in the model. Good comparison between the computer model results and the physical model data of the Los Angeles-Long Beach harbor basin has been obtained.
